  • Optical network element with Brillouin effect colorless wavelength shift
    Patent number: 8041219
    Abstract: A method of optical communication includes generating an amplified optical signal from at least a portion of a first optical signal having a first carrier wavelength, ?1. The amplified optical signal is applied to Brillouin media to stimulate generation of a Brillouin effect signal at a wavelength ?2. The Brillouin effect signal is modulated to produce a second optical signal having a second carrier wavelength, ?2. In one embodiment, the first optical signal is a downstream optical signal and the second optical signal is an upstream optical signal of a passive optical network.
    Type: Grant
    Filed: January 31, 2008
    Date of Patent: October 18, 2011
    Assignee: Tellabs Operations, Inc.
